A Cost Segregation Study Is More Than Finding Savings

The harder part is supporting how every material classification was identified, valued, and documented. The CSA Partners cost segregation study is engineered so the tax position is explainable if the work is ever scrutinized.

Engineered

Start with the property

Plans, cost records, systems, improvements, materials, and site conditions are evaluated through a property-level engineering process.

Documented

Build the evidence

Qualifying components are tied to field observations, construction information, asset-level detail, and the methodology supporting the allocation.

Defensible

Make the position explainable

Classification, valuation, and supporting schedules are assembled so your CPA has a clear record of how the tax position was developed.

Guaranteed

Stand behind the work

Every CSA Partners study includes 100% no-cost audit support and is backed by the CSA Partners Guarantee.

A defensible study is not a tagline. It is the result of the process behind every classification.

An engineering-based cost segregation study does more than apply shorter recovery periods. It identifies, values, and documents qualifying components within the property's depreciable basis.

The CSA Partners Standard

Four disciplines. One defensible study.

Every CSA Partners study is built to establish the property facts, support the tax position, and stand behind the work if it is ever examined.

Identify

Property review and asset-level identification establish what is actually in the building.

Engineer

Construction expertise and valuation methods support the appropriate recovery periods and values.

Document

CPA-ready schedules, methodology, and supporting detail create a clear audit trail.

Defend

Audit support keeps CSA Partners involved if the study is questioned.

SiteWize™ Property Asset Intelligence

Field verification strengthens the study.

SiteWizeâ„¢ creates a documented record of the physical property before classifications are finalized, connecting what was observed in the field directly to the engineering analysis.

01

Real-time data capture

Measurements and component conditions recorded on the spot.

02

Photographic documentation

Visual proof for every position, stored for the life of the study.

03

Construction-grade detail

Every classification traces back to physical evidence.

Savings Should Stay Found

A cost segregation study should do more than identify depreciation. It should be built to support the tax position behind it. That is why every CSA Partners study is backed by our audit-support commitment and the CSA Partners Guarantee.

BUT OUR COMMITMENT GOES FURTHER

If a CSA Partners study is audited and a significant depreciation position we identified is ultimately disallowed, we refund the engagement fee.

Savings should come with accountability.

Applies to the original engagement fee for the study in question and is subject to the terms of the applicable service agreement.

Frequently Asked Questions

How much does a cost segregation study cost?

Pricing depends on the property, scope, and level of implementation support required. CSA Partners offers Core, Standard, and Premium service levels so the engagement can match the complexity of your property and tax situation. Every engagement includes an engineered cost segregation report, bonus depreciation justification, and audit support. We start with a complimentary Benefit Analysis so you can review the estimated depreciation opportunity and recommended scope before moving forward.

What documentation do I need to provide?

Basic documentation typically includes the property address and acquisition date, purchase closing statement, current depreciation schedule if available, and building cost information. Construction drawings and detailed cost records are helpful but not always required. If documentation is missing or you are unsure what you have, CSA Partners will work with you to identify what is needed to complete the study.

Will a cost segregation study trigger an IRS audit?

A cost segregation study does not automatically trigger an IRS audit. When performed with engineering-based analysis and thorough supporting documentation, cost segregation is an established tax strategy addressed in the IRS Cost Segregation Audit Techniques Guide. CSA Partners builds each study with audit readiness in mind and provides 100% no-cost audit support following completion of the study.

How long does the study process take?

A cost segregation study typically takes about 3 to 4 weeks from engagement to final report delivery, depending on property complexity, documentation, and scheduling. The process includes document collection, property analysis, an on-site inspection when applicable, engineering analysis, and preparation of the final report. Expedited delivery is available with qualifying service levels when timing is critical.

How is CSA Partners different from other cost segregation firms?

CSA Partners combines engineering expertise, construction knowledge, property-specific analysis, and on-site verification when appropriate. Our team uses SiteWize™ technology to capture property-level details and support asset classifications with thorough documentation. Rather than focusing solely on maximizing reclassification, we build each study around accuracy, documentation, and defensibility. CSA Partners also provides 100% no-cost audit support following completion of the study, and every study is backed by the CSA Partners Guarantee.
